SAID LIEBERKNE 1 ATENT oF TYPE-CASTING MACHINE.

To (LIZ It'll-0711, it may concern-.-

Be it known that we, ROBERT DRUMMOND and WILLIAM C. LIEBERKNEGHT,citizens of the United States, and residents, respectively, of theborough of Brooklyn and of the borough of Manhattan, both in the cityand State of New York, have invented a new and. useful Improvement inType-Casting Ma chines, of which the following is a specification.

This invention relates to an improvement in type-easting machines, andis particularly directed to means for making low quads and spaces, withthe object in view of permitting the use of the type cast by the machinefor printing purposes without danger of the quads and spaces coming incontact with the print-ed surface.

A practical embodiment of our invention is represented in theaccompanying drawings, in which c Figure 1 is a view in front elevationof a )ortion of a type-casting machine of welllrnown and-approvedconstruction with our device for making low quads and spaces appliedthereto. Fig. 2 is a view in side elevation of the same. Fig. 3 is a topplan view with certain of the parts broken away to more clearly show theparts beneath them, the device for making the low spaces being in itsclosed position. Fig. 4 is a vertical section through the machine in theplane of the blade, showing the device for making the low spaces in itsopen position. Fig.5 is a top plan view of the same. Fig. 6 is a detailver tical section in the plane of the blade, show-- ing the parts in theposition shown in Fig. 3. Fig. 7 is a detail view showing the type, theen-quad, the em-quad, and the justification space or. blank. auxiliaryblade in top plan and face views, and Fig. 9 is a transverse verticalsection taken in the plane of the lock for the auxiliary blade.

The main blade {denoted by 1) for determining the width of the body ofthe type, quad, or space is operated in the well-known manner by thesliding bars 2 and. 3.

The blade 1 is surmountedby an auxiliary blade 4, which is permitted aslight longitudinal sliding movement thereon at predetermined intervalsfor opening and closing the top of the mold.

Specification of Letters Patent. Application filed October 31,1903.Serial N0. 179.290.

of its rearward movement'with Fig. 8 shows the lock for the PatentedMarch 26, 19 57 The forward end 5 of the auxiliary, 4 overlaps theforward end ti of the main blade a short distance below the face of themov-' able matrix-case 7 so that when the auxiliary blade is moved toclosethe top of the mold the metal within the mold will be stopped acorresponding space from the face of the matiix-ease to form a low quador space. i v

When the auxiliary blade 4 is at the limit respect to the blade 1, theface of its for "d end 5 will be in alinement with the face 01 theforward end 6 of the main. blade, thus permitting the metal within themold to flow into engagement with the type on the face of the movablematrix-case 7. v i i The mechanism which We employ for operating theauxiliary blade at predetermined intervals independent of the operationof the main blade to form low quads and spaces for the diilerentspacesviz., the err-quad; the em-quad, or the justificati0n-space-is asfollows: The auxiliaryblade 4 is provided with a recess 8. A earn 9,carried by the bar 10, fitted to slide in a suitable bearing 11, isarranged in position to enter the recess 8 at-pr'edetermined intervalsfor sliding the auxiliary blade forward independently of the main blade1.

The cam-bar 10 is connected at 12 to one arm 13 of a two-armed leverpivoted at 14 to swing horizontally, the other arm 15 of the said leverhaving a pin-and-slot connection 1.6 17 with an arm 18 of a secondtwo-armed lever pivoted at 19* to swing horizontally,

the other arm 19 of the last-named two-- 'armed lever carrying alaterally-extended controlling-bar 20. v c A The movable blade 4 isprovided withra recess 21, which is engaged and disengaged: by

a laterally-sliding lock 22,-carried by the main blade 1.. The movementof this look 22 is controlled by the movement of the rocking lever 1315, as follows: -A laterallysliding bar 23 has its outer end providedwith a pin-and-slot connection 24 25 with the arm 13 of the rockinglever 13 15. The inner end of this laterally-sliding bar 23 is providedwith two upwardly-extended arms 26 27 which engage the outer faces oftherearwardly-ex'tended arms 28 29, of the lock 22, This connectionbetween the lock and the 25 18- 19 and 13 1-5 fitted to slide into andout of the recess 21 in the under side of the movable blade 4, and adepressed portion 22**, adjacent to the lip 22 on or'over whichdepressed portion the bla e 4 may freely move 1n a longitudinal diorection when the lock 22 is moved laterally r 5 which is 20 20 of therocking lever 18 19.

to diseng e the ii 22* from the recess 21. The mec anism or operatingthe movable blade 4 to form the uads or the justification-spaces is asfol ows: The wedge 30, operated and which controls the movement of themain blade 1 in the usual manner'to form the pro er mold-slot for the'ustification-space, IS a so provided with a iug 31, which embraces thecontrolling-bar As the wedge is moved inwardly laterally with respect tothe mold-blades the lug 31 will engage the yielding stop 32, and as thewedge com letes its inward movement the two rocking evers will be rockedin adirection to slide the cam 9 into the recess in the movable biade 4for sliding the blade into position i to close the top of the mold-slotat a distance from the type on the face of the matrix-case.

Before the earn 9 is moved a suflicient distance to slide the movableblade 4 forward the lock 22 is withdrawn from the recess 21 the movableblade through the controllingbar 23. P

It is to be understood that the blade 1 is operated in the usual mannerby the sliding bars 2 and 3 to first bring it into position to form thespace of the required thickness and is then moved toward the mold-slotfor forc- 0 ing the space after ithas been formed out of "the mold-slot.This last forward movement of the blade 1 will bring the lock 22opposite the recess 21 on the movable blade, so that as the ge 30 ismoved laterally outward 1 45 it will, through the engagement of the lug3.1 with the yielding stop 33 on the bar 20, rock the two levers 18 19and 13 15 back to their normal position and draw the lock 22 into therecess. This same movement will also withdraw the cam 9 from the recess8 of the movable blade. thus permitting the two blades to be drawn backto their normal pos1- tion by the usual mechanism for withdraw ing theblade 1.

The means which we have shown for sliding the movable blade 4 forwardindepend- I ently of theblade 1 to form a low quad of a differentthickness than the justificationspace-as, for instance, the em-quad-isas 60 follows: The rocking lever 13 15 18 provided witlr'alaterally-extended controlling-rod. 34. The lever-arm 35 engages aielding stop 36 on the rod 34, which lever is inged'to swing verticallyon a pivot 37., carried by a Support 38 of the machine. The upper arm 39of this lever is connected through a rod 40 with theupper arm 41 of atwo-armed. rocking lever 41 42, pivoted at 43 toanother support 44 onthe machine. The lower arm 42 of the two-armed rocking lever 41 42 islocated in position to be engaged by the matrix case 7 when thematrirecasc' required point by the controlling mechanism for causing theem-quad to be formed. The engagement of the m'atrix-case 7 with the saidarm 42 will, through the connections above described, cause thehorizontal roclring levers 13 15 and 18 19 to be rocked into position tounlock the. movable blade 4 and slide it forward to close the upper endof the mold-slot as hereinbefore described. This movement will alsocompress the spring of the yielding stop 33 against the lug 31 of thehas been moved to the wedge 30 because of the rocking movement of thelever 18 19, so that when the case '7 is withdrawn from its engagementwith the arm 42 the parts willbe returned to their normal position bytheextension oi the spring-yielding stop 33 whcn it is permittedto exertits force. v

The means which we have shown for sliding the movable blade 4 forwardindependently of the blade 1 to form a low space of still anotherthicknessas, for instance, for forming an en-quad-1s as iollows: Atwoarmed lever has its lower arm 45 fixed to a rock-shaft 46, carried bya bracket 47, cured to the support 38, which arm 45 is err-- tended downinto position to be engaged by the matrix-case 7 when the matriiecase ismoved to a predetermined point by the controlling mechanism forpermitting the en quad to be formed. The upper arm of this lever is alsofixed to the shaft 46 and is connected by a rod 49 with one arm 50 ofanr angle-lever pivoted at 51 to a bracket carried by the support 38, theother arm 53 of the said angle-lever having a pin-and-slot connection 5455 with the connectingaod 4G, hereinbefore described.

The rocking levers 13 15 and 18 19, and thereby the lock 22 and earn 9,are operated through. the rocking lever 35 39 and rod 3-4 in a mannersimilar to that described with retercnce to the means for controllingthe male ing of the em-quad.

By the mechanism herein described we are enabled to form quads and.spaces the faces.

of which will be spaced a considerable distance from the faces of thetype without interfering with the operation of the ma chine in anyparticular.

It is evident that mechanism other than that herein shown and describedmight be employed for operating the movable blade for forming the lowquads and spaces. Hence we do not wish to limit ourselves strictly tothe structure herein set forth; but

-- blades to form a low What'we claim is' I 1.
